Title: Methods and compositions employing unique mixtures of polar and neutral lipids for protecting the gastrointestinal tract and additional applications for surfactant replacement therapy and other conditions requiring rapid phospholipid _absorption to surfaces
Inventor: LICHTENBERGER LENARD M
IPC: A61K9/127
Filed: 1989-11-23
Abstract: Disclosed are methods employing compositions composed of unique mixtures of phospholipids and neutral lipids to treat the luminal lining of the gastrointestinal tract in the prevention or treatment of ulcerogenic processes such as peptic ulcer disease and inflammatory bowel disease.  Compositions including mixtures of saturated or unsaturated phospholipids, together with saturated or unsaturated triglycerides and/or sterols, are shown to provide a surprising ulcer protective efficacy in experimental models.  Further enhancement of activity is found upon the addition of a polyvalent cation or antioxidant to the various lipid mixtures.  The present invention also discloses unique methods employing mixtures of phospholipids and nutral lipids for surfactant replacement therapy in the treatment of the various forms of respiratory distress syndrome.  These compositions are shown to greatly enhance the surfactant replacement efficiency of surface-active lipids.  In this regard, experimental models have shown that both the surface-tension lowering effect and rate of phospholipid absorption to an air/liquid interface are accelerated by the addition of triglycerides and/or sterols to mixtures of saturated or unsaturated phospholipids.  Such compositions are therefore theorized to give new and enhanced therapeutic value to the use of surface-active lipids for surfactant replacement therapy in a subject without risk of immunogenic response.  The subject methods also comprise a simple, rapid and inexpensive means for the deposition of polar lipids to a variety of air/liquid interfaces.

Title: Master cylinder
Inventor: ZANDER RICHARD A
IPC: G01F23/74
Filed: 1989-12-06
Abstract: ABSTRACT A master cylinder having a housing with a first bore therein for retaining a pair of pistons which move in response to an input force and develop fluid pressure to effect a brake application.  A second bore in the housing carries a differential area piston connected to the pressure chambers.  A reed switch retained in the housing is aligned with a first magnet located on a float in a reservoir and a second magnet is attached to the differential area piston.  A ferromagnetic shield located between the reed switch and second magnet has first and second openings located in a plane on either side of the reed switch.  Should a failure occur in either pressure chamber, the differential area piston moves to allow magnetic field to pass through the openings in the shield and activate the reed switch to develop a warning signal and inform an operator of a failure mode condition in the master cylinder.

Abstract: ABSTRACT OF THE DISCLOSURE                 A combination drill bit A drill bit for drilling a hole in the ground, with cutting elements annular-cutting a core  which when it has reached a certain height, is continuously crushed by teeth on rolling cones. By combining said two processes, cutting and crushing, in  this manner  an  improved drilling advancement  is achieved as compared to separate use of said processes. The cutting elements show relatively small variations as to radial positioning, which renders it possible to find a common approximately optimal rotational speed of said elements.  Core  is weak and may be drilled out relatively easily by the aid of crushing, as compared to drilling pure holes. This is due to the fact that the core geometry causes a more efficient growth of fractures  for  each  tooth penetration,  and that  the core,  due  to  annular  cutting  is  free  from  radial tensions from the surrounding rock formations. In order to increase the life of the PDC cutting element the mechanical strength of said elemen is improved due to the fact that the edge of said element is rounded with a small visible radius.
